B2713

DTC B2713

Circuit Description
The body control module (BCM) controls the automatic transmission (A/T) shift lock control solenoid ground circuit and monitors the voltage of the ground control circuit.

DTC Descriptor
This diagnostic procedure supports this DTC:
DTC B2713 Gearshift Lock Circuit High

Conditions for Running the DTC
The controlled ground circuit of the A/T shift lock control solenoid must be ON.

Conditions for Setting the DTC
^ The BCM detects the controlled ground circuit voltage is approximately equal to battery voltage in the ON state.
^ The condition above must be present for more than 0.3 seconds.
^ This DTC will be set after 20 seconds due to possible false failures.

Action Taken When the DTC Sets
The BCM stores DTC B2713 in memory.

Conditions for Clearing the DTC
^ The BCM determines that the controlled ground circuit of the A/T shift lock control solenoid is no longer shorted to battery voltage.
^ A history DTC B2713 will clear after 100 consecutive ignition cycles if the condition for the malfunction is no longer present.
^ A scan tool may be used to clear the DTC.

Diagnostic Aids
^ If DTC B2713 is a history DTC, the fault may be intermittent.
^ These conditions may cause an intermittent malfunction to occur:
^ An intermittent short to battery voltage in the controlled ground circuit of the A/T shift lock control solenoid
^ The A/T shift lock control solenoid coil is shorted to battery voltage internally.
^ The BCM is shorted to battery internally.

Test Description
These numbers correspond to the step numbers on the diagnostic table.
2. Listen for an audible click when the A/T shift lock control solenoid operates. Command both the ON and OFF states. Repeat the commands as necessary.
3. Tests for an internal short of the A/T shift lock control solenoid. Command both ON and OFF states. Repeat the commands as necessary.
4. Tests if voltage is constantly being applied to the A/T shift lock control solenoid control circuit.





8. The BCM must be programmed for the vehicle regular production option (RPO) configuration.
